    Chemistry stinks - class smelling activity

    This class practical introduces concepts of chemistry and smell. A number of common chemicals with distinctive smells have been chosen to help students get their nose around different functionalities in chemistry. This is done via a series of solutions, which can be smelled using smelling sticks.

    Oxidation numbers

    This activity introduces oxidation numbers by giving a conceptual foundation for them in terms of electron accounting and polar bonds. It then shows how the model used so far needs refining.

    Formal charge

    This activity introduces formal charge – a useful tool which otherwise might not be taught. The formal charge model treats bonds as pure covalent, in contrast to the oxidation state model which treats bonds as ionic.

    Covalent bonding

    This activity seeks to develop an understanding of covalent bonding in terms of energetic stability rather than full shells.

    Ionic bonding

    An explanation often given for ionic bonding is that atoms lose or gain electrons to achieve noble gas configurations. This activity evaluates that as a complete explanation.
